SOUND-RECORD FOR TALKING-.MACHINES. 1

Specification of Letters Patent.

Application filed September 6,1910. Serial No. 580,670.-

Patented Apr. 22, 1913.

To all whom c't'may concern:

Be it known that I, CLARENCE S. WICKES, a citizen of the United States,and a resident of the borough of Merchantville, State of New Jersey,have invented certain 'new and useful Improvements in Sound-Records forTalking-Machines, of which the following is a full,clear, and exactdisclosure, reference ess of-manufacture, and isliable to warp. duringits subsequent use. This warping ap:

to the marginal: rib, whereby as the record being had to theaccompanying drawings, forming a part of the followingspecification.

thereof; and to provi e other improvements,

as will appear hereinafter.

It has been discovered after numerous exriments, that a compressed diskrecord aving arelatively' thin body portion provided upon its back witha marginal rib and with radial or transverse reinforcing ribs.extendingfrom the central portion of the rewrd and connected with themarginal rib at their outer ends, tends to warp as it cools after beingtaken from the press in the procpears to be due to the fact that theouter ends of the radial or transverse ribs are. connected cools, therim of the record is drawn slightly rearwardly, and the face of therecord is caused to assume a convex shape.

One of the objects of this lnvention is to overcome this tendency towarp, which is found in the ribbed back record as heretoforeconstructed, during its process of manufacture and during its subsequentuse, and I have found that whenthe i marginal rib is omitted in a recordof this kind and. the

' radial ribs are retained, that this tendency of the record to warp iseliminated. This omission of the marginal rib, however. obviouslydeprives the record of some of its strength at its edge.

I have also. discovered after various experiments, that a thinribbed-back record having the desired qualities of rigidity and strengthand having a flat recorded surface, may be provided by constructing therecord with a marginal rib and also Wltllradial or transverse ribsextending from the central portionof the back of the record outwardly,and the outer ends of which are not connected with the marginal rib.

Furthermore, I have discovercdthat in the latter construction and alsoin the construction in which the marginal rib is omitted, or in otherconstructions, transverse or radial ribs which have their outer endsconnected to the marginal rib or extending from the margin of therecord, and their inner ends spaced from the central portion of therecord, may be used to advantage to strengthen the record and to preventwarp- 1ng.;

In the accompanying drawings, Figure 1 is a diametrical section of asound record constructed in accordance with this invention; Fig. 2 afragmentary bottom plan vieW or rear elevation of the same; Fig. 3 afragmentary top plan view or front elevation of the same; Fig. 4 adiametrical section of a modified form of this invention; Fig. 5 a

fragmentary bottom plan view of Fig. 4, the top plan view of Fig. 4being the same as shown in Fig. 3; and Figs. 6, 7, 8 and 9 arefragmentary bot-tom plan views of various other modified forms of thisinvention.

Referring to. the drawings, -one embodiment of this invention comprisesa circular disk record 1, made in any suitable way of any suitablematerial, but preferably made in a well known manner by compressing be.-

tween two heated matrices a well knowning the usual s iral sound groove4, formed of lateral un ulations 'of uniform depth. Instead of the soundgroove 4 described, any suitable sound record might be applied to theflat annular face 3 of the disk.

35 jecting rearwardly from the back 'of the 1 preferably substantiallyin the plane ofthe" The record is preferably provided with the a usualcentral aperture 5, and the centralpon' tion of the face of the recordis preferably depressed within the recorded. surface 3, to form ashallow fiat circular recess 6, of substantially uniform depth andconcentric with the record. .This recess 6 is adapted to receive theusual label 7 which is secured place in any suitable manner. The back orunder side of the record is preferably provided wit-h a flat circularprojection 8, form'- ing a part of the body :of-the record. Thethickness of the projection 8 is. 'referably substantially uniform andsu stantially equal to the depth of the labelre'cess 6, in the face ofthe record; and the diameter of the projection is preferably, however,as shown, slightly greater than'the diameter of the recess, to preservea substantially uniform thickness throughout the body of the record. Inother words, the label recess 6 is formed by depressing the centralportion of the face of the record and correspondingly raising thecentral port-ion 8 of the back of the record a substantially equalamount. The

record is also provided upon its underside with a flat circular boss 9,surrounding and concentric with the central aperture 5 of the record,the diameter of the boss being only a smallflpart of the. diameter .ofthe projection, 8 of the back of the record, and being intended merelyto strengthen the record around its central aperture.

The record is preferably formedwith an annular -marginal rib 10,preferably prorecord, the lower :surface of the rib being lower surfaceof the boss 9, at the center of the record. This annular marginal ribmight be arranged to project 'forwardl fromthe front :of the record, ifpreferre Radial: ribs 11 are also provided upon the back of the record,the outer ends of these ribs being, spaced inwardly from the marginalrib, the inner portions of these radial ribs preferably overlapping. thecircular projection 8, upon the backof the record, and

the inner ends of the ribs being preferably spaced from the boss 9,surroundingthe central aperture of the record. The under surfaces of theribs 11 are preferably tangent to a plane coincident with the lowersurface of the boss 9, and tangent to' the marginal rib 10, throughoutsubstantially their fulllengths. The extremities of the ribs may betapered to meet the under surface of the body of the record.

Instead of construetin the record with a marginal rib as hereto oredescribed, the

marginal rib may be omitted. as shown in:

Figs; 4 and 5,.thefrecord, being constructed in other respectsidentically as before or as hereinafter described. When the marginal ribis omitted, the record is obviouslymore ments of ribs.

and arranged. in; a

e of straight.

fragile, b ut may be found, when constructed offsuitable material, to bedurable enough for ordinary purposes. 1

In Figs. 6, 7, 8 and9 are shown bottom tion, in which the body portion2v of the record is constructed in eachinstance as v heretoforedescribedand shown in Figs. 1 to 5, but in which, theback of the recordis provided with var'ious'forms and arrange- The under surfaces of allof the ribs in these modified forms are preferably tangent or coincidentwith the plane,

of the lower surface of the central boss 9.

The record shown in- Fig. 6 is provided on its back with a marginal rib.10 and with radial ribs 11, which maybecalled in this connection innerribs, extending outwardly from the central projection ,8 and havingtheir outer ends spaced fromthe marginal rib 10, as heretoforedescribed, and also with comparatively short outer radial ribs 15extending from the marginal rib 10 inwardly and having their inner endsspaced from the raised portion 8 of the back. In thisconstruction the-'outer ribs alternate with and overlap. the inner ribs, or, inotherwords, the alternate ribs are oppositely disposed staggered formationaround't-he' record. The recordv shown in Fig. 7 is similar tovtherecord shown inFig. 6, just described,

except that in the space between each two I adjacent outer radial ribs15 are two inner radial ribs 11.

The record shown in Fig. 8 is similar to that shown in Fig; 7 and justdescribed, except that in the space between each two adjacent innerradial ribs 11,are two outer radial ribs 15. Y

The record shown in. Fig. 9 is similar to the record shown-in Fig 6,heretofore'described, except that in this case the inner and outer ribs11 and 15 are curved instead The ribs are shown curved. simply toindicate that ribs other than straight may housed, and the curved formshownis only one of many forms that'ob- ,viously might be employed andwhich might v be found to possess some advant-agesfor some purposes overthe'stral'ght ribs; The invention, therefore, is not limited to any.

include all forms. 7

It is to be understood that in each of the various forms of recordsdescribed above, all of the ribs, the projection 8, and the boss 9,arepreferably integral with the bodyofthe record, and that the record.as a whole, in-

tion might also be applied, however, to any particular form of rib, butis intended to record, whether compressed "-or not, and whetherhomogeneous or not; for instance, itmight be applied. to a cast orcutrecord or to a record having a layer of paper or cardboard embeddedor inclosed in prefer mercial sound reproducing record is pro. ducedwhich for any given material and for.

anygiven area of face or recorded surface has-a body portion of minimumthickness, and has consequently a minimum mass or bulk, butwhich issufficiently rigid and durable for all. requirements.

Only a few of the many this invention may be embodied have beenshown,.but these. forms are thought to be suflicientto illustrate theinvention and to indicate that the invention is not limited to anyparticular construction described, but

might be applied in various forms without departing from the spirit ofthis invention or the scope of the appended claims.
